Plas Teg

Plas Teg was built in about 1610 by Sir John Trevor I, a prominent courtier of King James I, and is regarded as one of the finest Jacobean houses in Wales, and the finest in North Wales. Sir John died in 1630 and his wife in 1643, leaving the house unoccupied just as the Civil War broke out; it was twice raided by Parliamentary troops. The house nonetheless passed down through Trevor descendants for generations, and the family continued to live there into the early 20th century.

The decline began in the 20th century. During the Second World War the house and outbuildings were requisitioned by the War Office to house soldiers (one account has it sold to the War Office in 1930), and it was in this period that the decay took hold. In 1945 Plas Teg was sold to Dodds the auctioneers, who used it as a furniture store, and by the mid 1950s it was described as an estate of advanced decay.

In 1986 Cornelia Bayley paid £75,000 for the house. By then the roof had gone, trees were growing into the building and birds were flying around inside. She carried out a programme of works costing £400,000, half of it funded by Cadw, and within ten months of buying it had begun opening the house for tours. Plas Teg later featured on Channel 4's Country House Rescue, and Bayley once confessed to the Daily Post that she had become a "slave" to the sprawling mansion she had rescued, keeping it going for decades at great physical and emotional cost.

Plas Teg's haunted reputation was cemented by television. Most Haunted filmed in the house, as did a Girls Aloud ghost-hunting programme, and the mansion has since appeared in Britain's Scariest Hauntings and in Past Hunters, a Ghost Dimension series. Between them they helped make Plas Teg one of the most investigated houses in Wales, and for years events companies such as DeadLive ran public ghost hunts there, billing it as Wales's most haunted Jacobean mansion.

The reported phenomena are consistent across visitors and investigators: laughter and voices in empty rooms, footsteps, the sound of dogs barking where there are none, objects that move, sharp drops in temperature and, more subjectively, sudden and unexplained changes of mood. The Woman in White is claimed to have been seen both in the grounds and on the A541, and the Regency Room is the space most often singled out for oppressive feelings and reported activity.

A fair sceptical note: many of the stories were told and retold by Cornelia Bayley herself, a gifted storyteller who understood the value of a good ghost to a house that needed paying visitors. The Dorothy and Iorwerth tale, the well drowning of 1815 and the tally of fifteen ghosts are all legend rather than documented history, and different tellings disagree on the details. What is not in doubt is that Plas Teg, half-lit and full of antiques on a winter evening, was an extraordinarily atmospheric place to spend a night, which may be all the explanation many of its visitors need.

Plas Teg is not currently open to the public. In 2022 the house closed for major renovation works, and in early 2025 its contents, Cornelia Bayley's remarkable collection of antiques and curiosities, were sold in a series of auctions by Rogers Jones & Co, described as a once-in-a-generation house clearance, with proceeds going towards the care of the property and its owner. The North Wales press reported at the end of 2025 that the house remained closed with no reopening date announced, and there were no public ghost hunts or tours at the time of writing.

What you can still do is see the house from outside: Plas Teg stands right beside the A541 near Pontblyddyn, and its tall, symmetrical Jacobean front is a striking sight from the road, particularly on a misty evening. Please respect that it is private property. Mold, a few miles to the north-west, is the nearest town and the obvious base, with Wrexham and Chester within easy reach for a wider choice of places to stay in and around Flintshire.
